"Tonight, but not this instant," Bruce clarified. "You've been wearing the suit. You know more about the situation out there than I, at this moment." Which was as close as Wayne could come to 'and so I want to coordinate.' It was only good planning - coordinating efforts, sharing information and strategy - but getting an admission of weakness out of Batman was like pulling teeth.
"I've been abroad. Business, officially." Unofficially? Training. Testing himself. Again, as close as Bruce could skirt to an explanation for his absence without crossing into 'apology' territory.
